There are numerous apps and tech tools on the market to translate foreign languages. But sign language is a different matter. There is a major communication gap between hearing-impaired people and those who can hear.

An all-deaf team of entrepreneurs from the Rochester Institute of Technology is hoping to bridge that gap with the MotionSavvy Uni, a tablet case embedded with Leap Motion's gesture-sensing technology.

When someone signs in front of the tablet, Uni's software detects the sign and checks it against the growing database of signs....

To enable true conversation between a deaf person and a hearing person, the software can transcribe spoken word into text so it can be easily read.
